Abstract

The invention discloses a green phosphating preservative treatment liquid suitable for a steel surface as well as a preparation method and application of the green phosphating preservative treatment liquid. The green phosphating preservative treatment liquid comprises the following components: a compound preservative, a phosphating film transforming agent, a complexing agent, magnesium chloride, an emulsifier, a penetrant, ethanol and pure water. The invention has the following advantages: the components can generate a correlative synergistic effect, a firm protective film taking ferric phosphate as a main body can be formed on an interface, and the compact thin molecular film is insoluble in water, high in hardness and good in adhesive force, and can better promote chemical reaction and improve chemical properties under the action of metal and an oxidizing medium; the dissolving dispersity of the green phosphating anti-corrosion treatment liquid can be remarkably improved, the good binding force between the steel surface and a coating and the anti-corrosion and anti-corrosion effect are enhanced, and use is safe and convenient.

Description

technical field [0001] The invention relates to the technical field of steel structure material surface protection, in particular to anti-corrosion surface treatment technology. Background technique [0002] Metal corrosion is a phenomenon in which metal materials undergo chemical or electrochemical reactions with oxygen, moisture and other surrounding media in the atmosphere under the influence of certain environmental conditions (such as temperature and humidity) and are corroded and damaged. Usually refers to the corrosion of metal materials, and its corrosion products are called rust. The direct and indirect economic losses and harms caused by the corrosion of metal materials are enormous. [0003] The pre-painting process of steel structural parts is a very important work content for corrosion protection and surface technology. Coating and pre-painting anti-corrosion technology is a commonly used anti-corrosion technology for steel structural parts, and one of the key...
